HARNESS- BUCKLE.

SPECIFICATION formingpart of Letters Patent No. 621,617, dated. March 21, 1899.

Application filed May 13,1898. Serial No. 680,579. (No model.)

To all whom t may concern:

Bc it known that l, JACOB POLKA, of Smith Centre, in the county of Smith and St-ate of Kansas, have invented a new and Improved Harness-Buckle, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved harness-buckle more especially designed for use on traces, hip-straps, crupperstraps, and the like and arrangedfor conveniently and securely fastening the end of the strap or trace to the buckle without accidental disconnection of the end.

The invention consists' of novel features and parts and combinations of the same, as will be fully described lhereinafter and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similiar characters of reference indicate corresponding parts in all the figures. vFigure l is a' front face view of theimprovement. Fig. 2 is a rear face view of the same.

- Fig. Slis a longitudinal sectional view of the same on the line 3 3 of Fig. 2, and Fig. t is a similar View ofthe same with parts in a different position.

The improved harness-buckle is provided i with two parallel side bars lA A', connected tion.

with each other at their front edges and near their ends by cross-bars B B', as is plainly indicated in the drawings. The rear edges of the side bars are also connected with each other by cross-bars C, D, and E, of which the cross-bar C is located opposite the cross-bar B, and the cross-bar D is engaged by one end of a strap G, formed at its other end with apertures G', adapted to be engaged by a pin F', projecting from one end of a lever F, loosely fulcrumed on the Cross-bar E to permit the lever to move slightly in a longitudinal direc- The end of thelever F at the pin F' is beveled to engage a like bevel C' on the inner edge of the cross-bar C, so that when a pull is exerted on the strap G in the direction of the arrow d' at the time the pin F' engages one of the apertures G' then the lever slides in the same direction, and the bevel on the end of the lever lits snugly against the bevel C' of the fixed cross-bar to prevent the lever from swinging and the pin F' from disengaging the aperture Gr'.y Thus as long as there ver being provided with the pin F', above..

mentioned, and the rear end'of the lever F being provided with a cross-bar F2 at the rear of the front cross-bar B', so as to form, with the latter, a passage for the free end G2 of the strap G. i

In order to permit the longitudinal move' ment of the lever F, as described, the pivotal opening of the lever is elongated to permit longitudinal movement thereof for the purpose described.

, The cross-bar B' is beveled at its inner face in an outward direction, and a similar bevel is on the cross-bar F2 of the lever, so as to form a ready entrance or opening for the free end of the strap G.

The harness-buckle, as described, is very simple in construction, can be cheaply manufactured, is not liable to get out of order, and prevents accidental opening of the buckle tongue or lever F.

It will further be seen that by having the lever F constructed in the manner described the lever when moved into the position shown in Fig. 2-that is, withits pin F' engaging one of the apertures G'-t'henthe other end of said lever swings in t-he opposite direction, so as to form a passage-.way between the crossbars F2 and B'. By having a separate crossbar D for attaching the strap the latter need not be cut away and can be left the full width.

The cross-bar Bis su fciently widened at the middle (see Fig. l) to form a stop and guard for the pin F' to prevent foreign matter from catching on the pin. Furthermore, when strain is on the lever F and the beveled end of the lever engages the beveled end of the cross-bar C then the cross-bar G limits a possible. inward swinging of the pin end of the lever, and thus holds the beveled ends in contact. Y

Having thus fully described my invention,

-I claim as new and desire to secure by Letters Patentl. A harnessfbuckle, comprising parallel side bars, cross-bars connecting the front edges of said side barswith each other, an end IOO cross-bar for the rear edges of the side bars, an attaching cross-bar for receiving a strap, and a lever fulcrumed at or near its middle on a pivot cross-bar, said lever being provided at its inner end with a pin for engagement with one of the apertures in the strap, the 0pposite end being formed with a cross-bar operatin g in conjunction with the rear cross-bar at the front of the buckle, to form a passage for the strap, substantially as shown and described.

2. A harness-buckle, comprising parallel side bars, cross-bars connecting the front edges of said side bars with each other, an end cross-bar for the rear edges of the side bars, an attaching cross-bar for receiving a strap,

and a lever fulcrumed at or near its middle on apivot cross-bar, said lever being provided at its inner end with a pin for engagement with one of the apertures in the strap, the opposite end being formed with a vcross-bar operating in conjunction with the rear cross-bar at the front of the buckle, to form a passage for the strap, said lever being loosely fulcrumed and adapted to abut With its forward edge against the forward cross-bar at J[he rear edges of the buckle sides, substantially as shown and described.
